Maybe through some custom CSS or third-party scripting. There might be a way to identify based on user Id if someone is the author or not, and then to hide the like button to only the author. 

No way to stop the points they get unless you remove the functionality. Once the points are applied, you can’t roll them back (althought it’d be a good API feature for them to add, in which case you could build an automation with Zapier or similar tools to undo any points he’s giving himself)

That is correct, @DannyPancratz, thank you for helping our user!

@Vanessa_MEO - This would be difficult to achieve because I imagine more users like their own posts, so while it might be possible to remove likes for a single user, this would also happen at other times. This would necessitate a change in our API or a new functionality, such as adding a new feature that prevents users from liking their own posts.

If you believe that’s something valuable to your community, could you create this as idea in our community and give some more details on your use case? 

Let me know if there are any other questions.
